Examples of org.objectweb.asm.MethodVisitor.visitMethodInsn()

org.objectweb.asm.MethodVisitor.visitMethodInsn()
Visits a method instruction. A method instruction is an instruction that invokes a method. @param opcode the opcode of the type instruction to be visited. Thisopcode is either INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE. @param owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}). @param name the method's name. @param desc the method's descriptor (see {@link Type Type}).

  @Override
  public void pushInt(ComputeMethod method) {
    MethodVisitor mv = method.getVisitor();
    mv.visitVarInsn(ALOAD, ptrLocalIndex);
    mv.visitInsn(SWAP);
    mv.visitMethodInsn(INVOKEVIRTUAL, vectorClass, "getElementAsInt", "(I)I");
